(A) Hematoxylin and eosin staining of xenograft PMC42-LA tumor; (i) low magnification at 4× (ii) high magnification at 10×. (B) Representative images (20×) of EpCAM (red), Vimentin (green), and nucleus (blue) staining in PMC42-LA derived tumor from mice. Ubiquitous expression of EpCAM was observed across the cell junctions whereas ~4% vimentin-positive cells were distributed randomly across the whole tumor sectioned slide as well as being present around the necrotic area of tumor. N, necrotic area. Scale bar, 50 µM.
